Types of wood shores
Douglass fir, yellow pine
Maximum length of a wood shore
10ft. By 4x4
I type beam
Strongest beam. It provides direct pressure . Can be welded in place . But shoring watch must be in place
K type beam
Second strongest beam. Anchor points needed to set. AKA triangulation . Use carpenter square to cut angles
H type beam
Weakest of 3 designs. AKA cross axial due to design. And easily dismantled.
Shoring watch
Monitor conditions of shoring. Must have comms. Batten. And plug kit
Shoring batten
Used for quick accurate measuring of shoring
Fire main pressure
135-185 psi range
4 types of patching
Soft patch. EWARP. Banding. Jubilee.
Pipe patching
Rubber gasket. Wedges. Saws. Mauls. Hatchets.
Soft patch
Holds 150 psi. Never use for JP5. Rubber gasket and goes 2” pass the damaged area. Not for pipeline or equipment
EWARP
emergency water activated repair patch.hold 150 psi. Not to exceed 300 degrees. And hardens in 30 min.
Banding
Hold 150 psi. Faceshield and gloves needed. Needs 3 bands.
Jubilee
